Background technique

Setting for the two is supported with Wireless Fidelity (Wi-Fi) and third generation partner program (3GPP) mobile broadband Standby surge is done honest work change from the perspective of user and operator from 3GPP network to Wi-Fi network unloaded cell network industry It obtains more and more interesting.Such unloading can be referred to as " business guidance ".

From the perspective of operator and terminal user, using Wi-Fi or WLAN (WLAN), (the two terms are passed through Wear and be used interchangeably herein) just becoming more and more interesting from 3GPP network unloading business, and be advantageous.Its reason packet It includes:

Zero additional frequency: by using Wi-Fi, operator can obtain additional 85MHz and 5GHz in 2.4 5 GHz bands Almost another 500MHz in frequency band.

Zero cost: from the perspective of operator, Wi-Fi uses free unlicensed frequency.In addition, from capital cost and From the perspective of business is spent, the cost of Wi-Fi access point (AP) is substantially less than the cost of the base station 3GPP.Operator can also benefit With the AP disposed in " hot spot " (for example, railway station, airport, stadium, shopping mall etc.).Most of terminals are used Family currently also gets used to being in (this is because it is usually unified expense that home broadband, which is ordered) and public place uses free Wi- Fi。

Charging in mobile telecom network

Charging in mobile telecom network is usually by core net node and service network node (including telecommunication network) One or more is performed.Charging can be divided into online charging and offline charging.In addition it is possible to use strategy and charging rule Then function (PCRF) and/or mobile network's customized application enhance logic (CAMEL) Lai Jinhang charging.

There is discussed herein the general aspects of the charging in mobile telecom network, however, reader can refer to 3GPP TS 32.240,3GPP TS 23.401,3GPP TS 23.060 and 3GPP TS 23.078 are to obtain more information.

For gateway general packet radio service (GPRS) supporting node (GGSN) (or PDN-GW) and online charging system (OCS) main principle of the diameter credit control session between is as follows.GGSN (or PDN-GW) is asked with such as session request, service The difference of summation session deletion etc., which is acted to OCS, initiates different types of diameter credit control (CC) signaling.GGSN (or PDN-GW) from OCS receives quota, and may need to request more quotas when the current quota of UE (or order) starts and completes.In above-mentioned Appearance is only example, and other different arrangements are also possible.

Pass through CAMEL Application Part (CAP) between Serving GPRS Support Node (SGSN) and CAMEL service environment (CSE) Another main principle of the diameter credit control session of interface is as follows.SGSN is in packet data protocol (PDP) context activation or position Test point (DP) is initiated after context changes.SGSN receives one or more Apply Charging GPRS signals from CSE, in example If time quantum etc. includes different trigger condition.Per when a triggering condition is met, Apply Charging report then will be sent to CSE GPRS is accused to receive another Apply Charging GPRS signal or CSE for releasing session.Above content is only example, and other Different arrangements is also possible.

Wi-Fi framework

Fig. 3 a and Fig. 3 b show the simplification example of Wi-Fi framework.Fig. 3 a shows user plane, and Fig. 3 b shows control Plane.

Referring to Fig. 3 a, being used in user plane 300 and simplify very much construction, wherein UE/STA 302 is connected to AP 304, AP 304 can be directly connected to the network 306 of internet etc. and be connected indirectly to using 308.Referring to Fig. 3 b, controlling In plane 310 processed, AP 312 is connected to the network 314 of internet etc..Wi-Fi access point controller (AC) 316 is connected to Network 314, and manipulate the management to AP 312.One AC usually manipulates the management to multiple AP 312.Via authenticating, award It weighs with charging (AAA) entity and manipulates the safety and/or certification of user, AAA entity is usually by dial-up remote management user (RADIUS) 318 is serviced to provide.

Wi-Fi/3GPP integration mechanism

In the presence of multiple integration mechanisms for integrating Wi-Fi and 3GPP.It should be noted again that other nothings can be used Line access, but it is discussed in detail the concrete condition of 3GPP and W-Fi herein.

Common authentication

The potential thought of common authentication is automatic in two wireless access networks (in this case, 3GPP and Wi-Fi) Certification based on subscriber identity module (SIM).Extensible Authentication Protocol (EAP) is to provide recognizing for the support to different authentication method Demonstrate,prove frame.Requested comment (RFC) as described in 3748 and later as updating RFC 5247, which is directly carried on number According on link layer (DLL) and currently widely disposing in a wlan.EAP frame defines the authenticating party different more than 40 kinds Method, and EAP-SIM, EAP authentication and key agreement (AKA) and EAP-AKA ' are just being become widely available in UE and network Method.The benefit of common authentication be user need not play an active part in verification process (this will increase to the side Wi-Fi guide more business Chance), and for network central control pave the way.

User plane (core net) is integrated

Wi-Fi user plane, which is integrated, to be provided to terminal user to mobile operator (when via 3GPP and via Wi- When Fi connection) chance of same services (for example, parental control methods and method of payment based on order) is provided.The solution It further include making from the part of mobile core unloading user plane and not all business requires to go to the possibility of mobile core network Property.

Different solutions is being standardized in 3 gpp.It has defined and covers since 23.402 version 8 of 3GPP TS Lid solution (S2b, S2c), while integrated solution (S2a) is current ongoing work.S2a, S2b and S2c instruction For the 3GPP interfaces/reference points title of PDN-GW.

RAN grades integrated

Other than above-mentioned common authentication method and user plane integrated approach, it is also based on about 3GPP and Wi-Fi The RAN information of both wireless access networks realizes that another grade is integrated via access selection.

The function of introducing referred to as wireless access, frequency and cell (RAFC) selection function, may be used as Wi-Fi and The information sharing point of 3GPP network." RAFC " function may be implemented as individual node or it can be used as it is any existing A part of node is distributed in 3GPP or Wi-Fi wireless access network.It is also implemented as the centralized function in a node It can or distribute to the function of multiple nodes.

Business guidance can be executed by considering the situation at each wireless access network.By using this abstract general Thought or even traditional UE are benefited in can integrating from Wi-Fi.For example, it is contemplated that having been coupled to 3GPP network and adopting With above-mentioned " Wi-Fi-if-coverage " (that is, when UE detects Wi-Fi, all selection Wi-Fi) access selection mechanism Traditional UE.When traditional UE attempts to connect to Wi-Fi network, AP and/or AC may be coupled to RAFC to request about 3GPP The information of the service quality (QoS) of active user in network.If it find that being used in the case where connection is switched to Wi-Fi RAN The QoS at family will decline, then can send refusal so that it remains connected to 3GPP RAN from Wi-Fi RAN to UE.As traditional UE When attempting access Wi-Fi, function can also be added between Wi-Fi RAN and 3GPP network to help to find correct service RAN node and relevant RAFC.If AP and eNB is co-located and has direct communication in-between rather than passes through By the communication of RAFC, then closer integrate can also be formed.It is this it is co-located in the case where another example be RAFC is implemented as the function in eNB.Similarly, it may be considered that AC, radio network controller (RNC), base station sub-system (BSS) Direct communication Deng between.

Inventors have realised that the new standard of real-time ordering information or metering data can be used to realize that business guides Or unloading.For example, about using the decision of which wireless access network can be based at least partially on metering data, the charging number According to may include following one or more:

The quota that zero user that can be used on 3GPP and/or Wi-Fi RAN orders is (that is, in specific time (for example, 1 Month) in available portfolio)

The cost of every kilobytes of zero data ordered for the user on 3GPP and/or Wi-Fi RAN

The Maximum Bit Rate that zero user that can be used on 3GPP and/or Wi-Fi RAN orders.This can be due in core net Throttling and change.For example, if using more than rated capacity (for example, 10G byte) in specific time (for example, 1 month), Then bit rate can reduce as minimum speed limit (for example, 128kb/s)

The remaining credit that zero user that can be used on 3GPP and/or Wi-Fi RAN orders

Zero remaining time ordered for the user on 3GPP and/or Wi-Fi RAN

Although working as it should be noted that above-mentioned example is related to guiding from the business of 3GPP RAN to Wi-Fi RAN Identical principle can be used when being transmitted from any RAN to another RAN.

In general, each subscriber for all RAN (including Wi-Fi) will have subscription plan (e.g., including high specific Special rate, data bucket, price of every kilobytes etc.).Inventors have realised that there is currently no for determining between differentiation technology The mechanism of valence (for example, competing the limited time) (this can be used for as needed guiding subscriber to particular technology).The differentiation It can also be beneficial to that there is the possibility for not only distinguishing 3GPP and Wi-Fi RAN but also distinguishing 3GPP wireless access technology (RAT) Property.

Signaling can use the signaling based on 3GPP control plane.RAN can be used to core net grade agreement or to now in this There is the extension of agreement.For example, meter can be provided when UE context is established and/or when creating and modifying radio bearer to RAN Charge information.

Therefore, metering data can be transmitted to RAFC 412 and/or UE 402 by existing interface or proprietary interface.

If sending metering data to UE 402, it can be selected RAN 404a-d.402 0, UE referring to Fig.1 1000 metering datas are received at the receiver 504 of communication function 500.It is based at least partially on the received metering data of institute, RAN Selector 506 selects one or more of more than 1002 a RAN 404a-d.It can be by UE 402 for example based on predefined standard Collection is selected automatically.In other words, UE 402, which can have, is stored in 508 for making RAN selector 506 select Wi- Fi RAN 404d is (if the quota of 3GPP RAN (for example, 3G RAN 404b or LTE RAN 404c) is completely used up or uses Specified limit) instruction.Alternatively, if more than the increased costs to threshold value of the data on current RAN, RAN selector 506 can choose RAN.It is alternatively possible to based on a period of time (for example, one month) about given UE 402 or order number RAN is selected according to using.Selection can be based on to for remaining time section, whether the prediction of residue quota enough (is matched based on residue Volume).Other standards can be used, and provided two standards are merely exemplary.

In other arrangements, UE 402 includes the user interface 511 controlled by user interface controller 509, user interface 511 are configured as that metering data is presented to user and receive the selection to RAN from user.In illustrative methods and device, User interface 511 may include following one or more: display, audio output, keyboard or touch screen.It is presented when to user When metering data, user can select RAN based on its demand.For example, user may want to select generally the least expensive wireless access Profile.Alternatively, compared with cost, user may think that bit rate is more important.

Once having selected for RAN 404a-d, so that it may send 404 from transmitter 502 to one or more RAN nodes The related data with selection.

One or more RAN nodes may include RAN node 412a, as shown in fig. 6, and can be configured as realization The function of RAFC 412.In other arrangements, RAFC 412 can be used as built-in function and be included in RAN node 412a.With choosing Select the data that related data may include the selected RAN of mark.In these cases, RAN node 412a is configured with The selection information that UE 402 is sent is for being connected to one or more RAN 404a-d for UE 402.

In other arrangements, data related with the selection of RAN 404a-d may include for being connected to specific RAN The instruction of 404a-d.Therefore, connection can be individually realized by UE 402.

Alternatively, as described below, related data may include the preference number that can be used by RAFC 412 with selection According to, but the final decision that RAFC 412 may have UE 402 to be connected to which RAN 404a-d.For example, selection information The one or more combinations that may include multiple RAN 404a-d or RAN 404a-d and the condition using each RAN (for example, sequence of preference).

If sent metering data to RAN node 412a (or RAFC 412), the RAN of RAN node 412a is selected Selecting device 606 can be configured as one of selection RAN 404a-d to be connected to UE 402.Referring to Fig.1 1, RAN node 412a are logical 1100 metering datas ordered for user are received at the receiver 604 of telecommunication function 600.

It is based at least partially on the received metering data of institute, RAN selector 606 selects 1102 RAN 404a-d.Selection can Using the selection criteria being retained in based on a part as RAFC 412 in node 412a.For example, RAFC 412 can be configured To select generally the least expensive RAN for a user or for a user RAN with optimal bit rate or at the two The RAN centainly to be compromised between situation.Other selection criteria are possible.In illustrative methods and device, RAFC 412 It can be configured as based on the combination of metering data and network constraint and/or requirement and select RAN 404a-d.Network constraint or It is required that may include network load information.In other words, if the load on such as RAN 404a-d is greater than threshold level, RAFC 412 can guide business far from RAN 404a-d.

The RAN connector 608 for forming a part of RAFC 412 selects the connection of UE 402 1104 to by RAN selector 606 The RAN 404a-d selected.It should be noted that RAN connector 608 can be configured in specific illustrative methods and device For UE 402 is connected to multiple RAN 404a-d.
